No power on trailer plug for lt signal on a 2500 hd gmc


get the standard wiring design

Yellow is the left turn signal on pin 2
Check trailer plug and see if correct colors used on trailer plug
Would suggest getting a 12volt probe so you can test the car socket when left indicator is going on - flashing
To check that the correct pin has 12volts flashing left on it.

You are probably going to find four wires together that do not have a plug on them. There should also be a tag taped on the wires showing that it is for the trailer. You will have to put a plug or some kind of connection on those wires.

Wiring diagram


If you are going from a 4 pin on your trailer to the 7 pin on the truck. You need to go to parts store or a department store (ex Wal Mart) and look in trailer section and find the adapter. Thats what I did. Also Remember if your lights don't work on trailer, check the plug to make sure its tight or check the fuse under your drivers side rear seat for that fuse box.

Installing a 7-pin trailer towing recptical on a 1991 Ford F150.


I believe you can look up the manufacturer of the trailer plug kit and find the wiring diagram there. On alot of the trailer plug kits, they have pics and diagrams in the package. The 7 pin plug (truck side) is available with the pig tail set up that plugs directly into the wiring harness for the lights. Then all you would have to worry about is the 2 wires for the electric brakes.
